Answer:
= 5n - 2
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₄ = 18 , then
a₁ + 3d = 18 , that is
3 + 3d = 18 ( subtract 3 from both sides )
3d = 15 (divide both sides by 3 )
d = 5
Then
= 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2 ← explicit rule
Answer:
For the length I think you meant 32, and if you did it is $14.40
If not and you meant length of 2 it is $0.90

Answer:
D
Step-by-step explanation:
It's 110. Since the one leg is not on zero it's not a full 160 instead you have to subtract 50 where the leg is.
Answer:
the answer would be 196.25
Step-by-step explanation:
Perimeter = 179/12 feet
Length = 35/8 feet
Perimeter = (2 × Length) + (2 × Width)
2(35/8) + 2Width = 179/12 feet
2Width = 179/12 - 35/4 = 37/6
Width = 37/(2 × 6) = 37/12
Simplify to get;
Width = 3 and 1/12
